has anyone experience a clucking sound when accelerating on a full stop? i wen't to the dealer ship and they told me right away it's the transmission. my understanding is if i have a transmission problem it should be making noise all the time... it only makes that noise when im going straight but when im making a right or left turn it dosen't make any noise at all...sometimes it's hard to believe the dealer ship.. i have about k 130,000 on it...2005 x3... if anyone experience this problem please let me know what i should do...
